Chapter 8: Bleeding 10/11/17
Bleeding – The average size adult has 5 to 6 quarts of blood and can safely donate a half quart.
- Rapid blood loss can lead to shock and death: loss of 1 quart in an adult and 0.5 quart in a child
External Bleeding
- Refers to blood coming from an open wound.
- Hemorrhage refers to a large amount of bleeding in a short time
- External bleeding can be categorized in 3 ways
o Arterial bleeding: blood spurts from the wound – most serious b/c a large amount
of blood can be lost in a short time; because of the high flow the ability to clot is
reduced
o Venous bleeding: blood flows from a vein flows steadily or gushes; easier to control
than arterial bleeding
o Capillary bleeding: most common type – blood oozes out - not serious and can be
controlled easily
- Body naturally responds to bleeding
o Blood vessel spasm – if a vessel is damaged, they draw back and constrict into the
tissue to slow the bleeding
o Clotting – platelets in the blood form a clot which serves as a protective cover for a
wound until the tissues heal themselves
Care for External Bleeding
- Wear gloves
- If no gloves, improvise with other materials
- Expose wound to find source of bleeding
- Place sterile gauze pad or clean cloth over wound
- Apply pressure
- Hold direct pressure for at least 5 minutes (direct pressure is the most effect method for
controlling bleeding)
- If the bleeding does not stop within 10 minutes
o Add dressings and press harder over a wider area
- Apply a pressure bandage over the dressing
- If the bleeding continues, call 911
o Consider using a tourniquet if severe bleeding from an arm or leg cannot be stopped
- Dispose of gloves and wash your hands
- DO NOT touch a surgical wound that is bleeding unless the bleeding is profuse
- DO NOT apply a pressure bandage so tightly that it cuts off circulation
- DO NOT give the person anything to eat or drink b/c that could cause nausea and vomiting
Bleeding is Controlled: What to Do
- Care for the wound
- If needed, seek medical care for: cleaning, stiches, tetanus immunization

Document Summary
Bleeding the average size adult has 5 to 6 quarts of blood and can safely donate a half quart. Rapid blood loss can lead to shock and death: loss of 1 quart in an adult and 0. 5 quart in a child. Refers to blood coming from an open wound. Hemorrhage refers to a large amount of bleeding in a short time. Place sterile gauze pad or clean cloth over wound. Hold direct pressure for at least 5 minutes (direct pressure is the most effect method for controlling bleeding) If the bleeding does not stop within 10 minutes: add dressings and press harder over a wider area. Apply a pressure bandage over the dressing. If the bleeding continues, call 911: consider using a tourniquet if severe bleeding from an arm or leg cannot be stopped. Dispose of gloves and wash your hands. Do not touch a surgical wound that is bleeding unless the bleeding is profuse.
